FLOORAND, THE LIKE PoLIsnInG ArPLmncE Application filed. mwember 12,1928, Serial No. 318,922, and in GermanyMay 11, 192s.

My invention relates to improvements in machines for use in polishingfloors, floor coverings and the like.' The polishing medium, preferablywax in form of paste is brought on the floor and consumed or worked uponby a 'brushlike instrument,

The means for waxing the floor are connected with the polishing means ina simple manner. By improvements of the said kind it 1s possible toevenly distribute suitable polishing medium as wax to the floor or'likesurface and to rub or polish the said surface after the polishing mediumhas been applied thereto. The alternate waxing and rubbing of polishingis done by lifting and lowering of the push handle. Further thearrangement has the advantage that the roller for putting on the wax isheld fast in one direction and freely rotatable in the other direction,so that the application ofwax to the floor occurs only by 7 3 the brush.

' The wax box rests withits discharge opening on the roller and is cutoff obliquely at the mouth. By putting it in the frame with itsdischarge opening upon the roller the projecting edge of the wax boxprevents a rotation of the roller in one direction and allows rotationthereof only in the opposite direction. Hence the wax is always appliedonly by rotation of the roller in one direction and at the same time theroller forms an obturation for the wax box and prevents waste of the waxpaste.

In the drawings:

Fig. 1 is a perspective of the apparatus,

Fig, 2 is a side elevation of the same,

Fig. 8 is a rear elevation of the frame with the roller and a piercingshaft,

Fig. 4: is a side view according to Fig. 3,

and

sition on the sides a a .Fig. '5 is a detail perspective of the wax boxwith a cover. V A u -shaped frame a, a a is. provided with a socketbwhich serves in a usual manner for the attachment of a push handle 0.sides a a of the frame (Figs. 1 and 2) have hearings on the journals dof a roller 6, and

the'roller is provided with a periphe'ralcover of cloth or felt. Thejournals d engage in slits g of arms 72 which carry-a brush body z'whichis secured to the heavy carrier plate It by screws. The carrier plate71, has a ring 7::

The

into which grips the hook Zof aturnbuckle or other longitudinallyextensible connect ing element m. The screwn of the turnbuckle isconnected to aring 0 of the shell 6. Frame a, at, a and brush body'z'are adjustably connected together by the turnbuckle m, because'the framesides a a lie fast against an angle iron 6, fixed to the carrier 71/1.The journals d are introduced by slits p transposed out of the centreline in the sides a a and easily exchangeable. gagement of the journalsfrom the slits p is impossible, because by the turnbuckle m a force isexerted which holds the carrierby the arms h.

In the form accordingto Fig. 3 and ithe axle d is longitudinally movablein the roller 6 andhas at one side a head 9' and on the other anut, bywhich the axle isfastened in its po- The roller e of wood has metalplates *8, which serves as bearings for the axle d, reposing in thesides 0 of. These plates 8 may be formed also as ball- 01;roller-bearing.

The frame a, a a is covered by a wall 6 at-the frontside and therearside has an attaching band .7 which is pivotallyconnected to the frameside a and has a snap at the free end to effect an elastic. connectionwiththe frame side al j I p In the receptacle formed by frame a, a a

from wall t and band 7 rests the box M,

which is filled with wax-paste, and the opening n of which is cutobliquely and can be closed by a sliding cover.

Thevessel u is made of tineplate and'has only smooth walls, so that thewax can freely move'in and drop from the vesseland' be Casual disenaxlein the applied by the roller to the floor. As shown in Fig. i the vesselu is arranged with its discharge opening on the roller 6, so that theroller closes snugly against the lower edges of the walls of the vessel.The edge :0 going over the roller, allows only a rotation of the latterin the direction of the arrow, but prevents an opposite rotation. Whenthe roller is revolved by movement of theapparatus in one direction, acertain quantity of wax may be drawn from the box as much as isnecessary at the moment, and the roller caused to spread a thin waxlayer on the floor.

In operation the frame a, a a is after unscrewing the turnbuckle m istaken from the brush part and the wax receptacle is brought into theframe and the ournals of the roller 6 are introduced in the slits 20 andthereafter into the slits g of the brush carrier h. By adjusting theturnbuckle the frame is joined to the brush carrier. The apparatusnormally rests on brush because the frame 7% is heavy and by a littlelifting of the push handle the was; roller may be lowered to the floorfor use and the brush lifted as will be understood.

A material economy in the wax employed is effected, the apparatus isvery readily manipulated and owing to its simplicity and solidconstruction always available.

Having thus described the nature of my said invention, I declare thatwhat I claim is:

1. A machine of the class described, having a weighted rubbing element,a roller mounted for rotation and arranged near one side of said rubbingelement, means to supply polishing material to said roller a handlewhereby said machine may be manipulated, said weighted rubbing elementwhen bearing on a floor 0; erating by its superior weight and incoaction with the handle to hold said roller in elevated position abovethe floor.

2. A machine of the class described, having a rubbing element providedat one side thereof with bearings, a roller mounted in said bearings, aframe pivotally mounted with respect to said bearings and roller andprovided with means whereby the machine may be manually operated andavessel serving as a reservoir for polishing material, said vessel beingdetachably mounted in and carried by said frame and having an openingwherewith to apply polishing material clirectly to the peripheralsurface of the roller.

8. In a machine of the class described, a polishing element having armsextending to one side thereof, a roller having axle journa-ls detachablymounted in said arms, a frame having side members detachably mounted onsaid axle journals, said frame being provided with means whereby themachine may be manually operated and a reservoir vessel for polishingmaterial carried by said frame and arranged to supply such material tothe periphery of the roller.

4. A machine of the class described, com-- pivotal axis of the frame,means carried by the frame to supply polishing material to the roller,the said frame having means whereby the machine may be manually operatedand a longitudinally extensible connecting element between said frameand said rubbing element and arranged to coact with said stop member tohold said frame and said rubbing element rigid, the one with respect tothe other.

5. A machine as claimed in claim 4, in which said connecting element isa turnbuckle and said turnbuckle is detachably secured at one end.

6. In improvements in floor and the like polishing appliances, a brushhaving a carrier member provided with an angle iron and also providedwith arms having slots, a frame for containing polishing material andhaving arms provided with slots, a roller having axle ournals mounted inthe slots of the frame arms and the brush carrier arms, and connectingmeans between the brush carrier and the frame to cause the latter tobear against the angle iron.

7. In floor and the like polishing appliances, a brush having a carriermember provided with an angle iron and also provided with arms havingslots, a container for polishing material and having arms provided withslots, a roller having axle journals mounted in the slots of the framearms and the brush carrier arms, and connecting means between the brushcarrier and the frame to cause the latter to bear against the angleiron.

In witness whereof, I affix my signature.

JOSEPH GAILHOFER.
